Our new fiberglass pool is set, filled, backfilled, and the pump is running. But, we are under an extreme heat wave and the contractor doesn't want to pour concrete with it so hot. So, in the meantime, I have no idea how to care for the water. We have a Pentair saltwater system installed, but no minerals in the water yet. The contractor probably won't be back for a couple weeks, as this heat is predicted to last a while. They have thrown some shock in, along with some scale inhibitor. Is there anything I need to keep an eye on? I had enough of looking at the dirt settled on the bottom, so I threw the Prowler in to give it a scrub. I didn't know whether vaccuuming is a good idea, since I really only know enough to be dangerous. I didn't want to mess up my pump or something. Any help is appreciated.
